BERNHARD KIHLHOLZ, OF ST. LOUIS, MISSOURI.

CHIMNEY-CAP.

Specification of Letters Patent No. 21,884, dated October 26, 1858.

To all whom 'ii may concern:

Be it known that I, BERNHARD KrHLHoLZ, of St. Louis, in the State ofMissouri, have invented a new and useful Machine for Preventing Chimneysfrom Smoking, to which I have given the name Chimney Smoke- Regulator;and I de hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l is a perspectiveview; Fig. 2 a perspective view ofl a section.

The lower part of the said machine forms a cover (see F ig. l, A) with apipe in its center (see Fig. I, B) of about six inches in diameter andabout a half of a foot in length, which cover is to be made suitable toany size of the top of a chimney and to be put on the same; the upperpart forms a joint of a pipe (see Fig. 2, A), suitable to the pipe onthe said cover, of about six inches in diameter and of about a foot anda half in length with a flange in shape of a funnel (see Fig. 2, B)measuring about eight inches in diameter, fastened around the latterpipe about an inch from its top, which latter is covered by a cap (seeFig. 2, C) in shape harmonizing with the above described flange butabout a half of an inch smaller in circumference, resting on threeholders supported by said flange. The edge of this cap is in one linewith the edge of the top of the pipe. The said cap and flangeareinclosed in a cylinder (see Fig. l, C), which is about a half of an inchlarger in circumference than said flange andas high as to inclose thesaid flange and cap about a half of an inch above the edge of the capand below the edge of the flange, resting on three holders, fastened onthe pipe below said flange.

This machine prevents the wind from blowing the smoke back into chimneysand rooms. The cylinder, it will be seen, shelters the cap and flange,and the smoke-pipe is again sheltered by the cap above and by the flangebelow, so that the wind will pass the so protected smoke-pipe withoutbeing able to penetrate into the interior and drive the smoke down thechimney. The cap being smaller than the flange the wind will on thecontrary promote the discharge of the smoke.

That I claim as my invention and desire to secure by Letters Patent is-The above described chimney smoke-regulator consisting of the pipe F,deflector E and cap I) inclosed in cylinder C, attached to cover A, thewhole constructed and arranged substantially as and for the purpose setforth.

BERNHARD K-IHLHOLZ.
